RoHS Low Viscosity Urethane Two Component Adhesive BZ-6100-5V-3

BZ-6100-5V-3: Low-Viscosity Polyurethane Adhesive for Intricate Assembly                                             

BZ-6100-5V-3 is a two-component polyurethane adhesive designed for intricate assembly applications, offering low viscosity, excellent flowability, and reliable bonding strength for complex components. With a lower mixed viscosity and balanced curing speed, it enables precise dispensing and complete penetration into narrow gaps and intricate structures, ensuring uniform bonding and consistent performance. This adhesive complies with RoHS standards and provides good temperature resistance and weatherability, making it suitable for both indoor and outdoor applications.

Key Product Features

1. Low Viscosity & Flowability: Initial mixed viscosity of 5000±1500 mPa·s allows complete penetration into narrow gaps and intricate component layouts, ensuring uniform bonding and eliminating voids in complex assemblies.
2. Balanced Curing Speed: Achieves surface drying in 2.5±1 hours and full curing in 4±1 hours at 25°C, providing sufficient working time for precise assembly while enabling efficient production cycles.
3. Adjustable Pot Life: 20±8 minutes at 25°C (adjustable) allows flexibility in working time, accommodating both manual and automated dispensing processes in intricate manufacturing.
4. Excellent Substrate Compatibility: Bonds effectively to aluminum honeycomb panels, sandwich panels, and delicate filter media, as well as plastic and electronic components, eliminating the need for surface treatments in most cases.
5. Low Water Absorption: ≤0.5% absorption in 24 hours ensures reliable performance in humid or outdoor environments, preventing delamination and maintaining bond integrity over time.

Directions for Use

1. Pre-potting Preparation: Calibrate scales, prepare potting tools, cleaning tools, check machine settings, check vacuum pump force, etc. 
2. Product Pre-treatment: Place product on a level surface or fixture. Remove dust, clean, degrease, and dry if necessary.
3. Accurate Proportioning: Manual operation requires precise mixing according to the specified ratio and recording. Machine potting requires calibrated ratios and first-article confirmation is recommended.
4. Mixing & Stirring: Manual operation requires thorough stirring or using electric stirrers to ensure homogeneous mixing. Machine potting requires sufficient stirring speed, adjust as needed.
5. Uniform Potting: Manual operation should be done in small, multiple batches to ensure uniformity. Machine potting should follow the programmed path for quantitative dispensing.
6. Inspection or Secondary Potting: After potting, visually inspect as needed. Perform touch-up, bubble removal, or secondary potting if required.
7. Curing: Allow the potted and inspected products to cure at room temperature or with heat assistance (recommended 60°C if needed), according to product and process requirements.
8. Final Product Confirmation: Perform visual inspection and performance testing as required by the customer.

Packaging & Shelf Life

1. Packaging: 25kg plastic drums, 200kg steel drums, and 1000kg IBC totes for both Component A (brown) and Component B (beige).
2. Shelf Life: 3–6 months from production date when stored sealed, protected from light at room temperature.
3. Opened Container: Use within 3 days for optimal performance; stir thoroughly before use if stored longer.
